Transformations of allylamine and N-allylacetamide on triosmium cluster complexes with hemilabile ligands
چکیده انگلیسی

The cluster complexes (μ-H)Os3(μ-OCR)(СО)10 (R = Me (1); R = Ph (2)) catalyze the allylic rearrangement of N-allylacetamide at room temperature. Microwave irradiation greatly (by more than several thousand-fold) accelerates the reaction between the solution of 2 and allylacetamide. The interaction of cluster 2 with allylamine both at room and elevated temperatures results in cleavage of the C–N bond and coordination of the allylic fragment to one of the osmium atoms with the formation of Os3(CO)9(μ,η2-OC-Ph)(η3-C3H5) (4) cluster.

The cluster complexes (μ-H)Os3 (μ-OCR)(СО)10 (R = Me (1); R = Ph (2)) catalyze allylic rearrangement of N-allylacetamide at room temperature. This reaction is accelerated thousands times at microwave irradiation of 2 and allylacetamide solution. The interaction of 2 with allylamine both at room temperature and when heated results in the C–N bond cleavage and formation of Os3(CO)9(μ,η2-OC-Ph)(η3-Allyl) (3) cluster.Figure optionsDownload as PowerPoint slide
